Last Time This Time 8 January • Introduction – Biogeography? – The Science of Biogeography • Who are You? • Major questions • History of Biogeography; • Methods – Why Geography instead of ? • Organization of Life • About spatial heterogeneity • Significant overlap but different perspectives • Systematics and Biological Nomenclature • This Class – the Semester • Perhaps: The Environmental Setting – Objectives – Logistics – Evaluation – Schedule • Reading: Chapter 1 & 2 in Lomolino et al.

Primary Question of Biogeography Who are you? • How and why does biological diversity vary • Name over the surface of the Earth? • Undergrad/Grad • What are you studying? (and thesis/dissertation topic for grad students) • Background in geography • Background in biology • What do you want to do when you graduate?

Eight distribution on islands is not size and isolation, as fundamental principles attend this domain: traditional island biogeography theory states, but 1. organisms are distributed heterogeneously in space and time economics.

Subphylum: Vertebrata • Domain: Eukarya (organisms which have cells with a nucleus) Class: Actinopterygii Order: Amiiformes • Kingdom: Animalia (with eukaryotic cells having cell membrane but lacking cell wall, • Amia calva L. multicellular, heterotrophic) Family: Amiidae • Bowfin in most of U.S. Genus: Amia • Phylum: Chordata (animals with a notochord, dorsal nerve cord, and pharyngeal gill Species: Amia calva L. slits, which may be vestigial or embryonic) • beaverfish, blackfish, cottonfish, cypress trout, • Subphylum: Vertebrata (possessing a backbone, which may be cartilaginous, to protect the dorsal nerve cord) freshwater dogfish, grindle, grinnel, John A. Grindle, • Class: Mammalia (endothermic vertebrates with hair and mammary glands which, in lawyer, marshfish, scaled ling, speckled cat, and females, secrete milk to nourish young) • Cohort: Placentalia (giving birth to live young after a full internal gestation period) western mudfish. Choupique is a common name • Order: Primates (collar bone, eyes face forward, grasping hands with fingers) used in Louisiana that was derived from the Choctaw • Suborder: Anthropoidea (monkeys, including apes, including humans; as opposed name for bowfin. to the , lorises, and tarsiers) http://www.flmnh.ufl.edu/fish/Gallery/ • Infraorder: Catarrhini (Old World anthropoids) Descript/Bowfin/Bowfin.html • Superfamily: Hominoidae (apes, including humans) • Family: Hominidae (great apes, including humans) • Genus: Homo • Species: Homo sapiens (high forehead, well-developed chin, gracile bone structure)

What is a Species? What is a Species? • Species are the fundamental taxonomic units of biological classification. Environmental laws are framed in terms of species. Even our conception of human nature is affected by our understanding of species. • Ernst Mayr: all the individual organisms of a natural population that generally interbreed at maturity in the wild and whose interbreeding produces fertile offspring. • But there are problems with this definition. • After thousands of years of use, the concept remains central to biology and a host of related fields, and yet also remains at times ill-defined. • "Right now we can only guess that the correct answer for the total number of species worldwide lies between 2 and 100 million," Michael Rosenzweig.
